Establishing Video Game Genres Using Data-Driven Modeling and Product Databases
2015
Establishing genres is the first step toward analyzing games and how the genre landscape evolves over the years. We use data-driven modeling that distils genres from textual descriptions of a large collection of games. We analyze the evolution of game genres from 1979 till 2010. Our results indicate that until 1990, there have been many genres competing for dominance, but thereafter sport-racing, strategy, and action have become the most prevalent genres. Moreover, we find that games vary to a great extent as to whether they belong mostly to one genre or to a combination of several genres. We also compare the results of our data-driven model with two product databases, Metacritic and Mobyga…
Understanding the Context of Teacher Professionalism in Education Systems Undergoing Transition – Kosovo Case
2014
Abstract This qualitative case study examines teacher professionalism in Kosovo in light of its rapidly developing education system. The study involves 14 teachers at the beginning of their careers (1-7 years of experience) examining teacher thinking against the evolving stages of teacher professionalism, namely pre-professionalism, autonomous professionalism, collegial professionalism and post-professionalism. The study reveals that Kosovo teachers reflect strong dominance of pre- professionalism and autonomous professionalism while they demonstrate a weaker reflection of collegial and post- professional aspects of teachers’ work. It provides insights for viewing teacher professionalism wi…
Value co-creation in health care : insights into the transformation from value creation to value co-creation through digitization
2016
This study explores the transformation of value creation into value co-creation and how the digitization of services plays a key role in this transformation within the health-care sector, which faces new challenges with the increasingly active role of the customer. Customers are becoming active participants in value co-creation and now have expectations based on their needs from the service. The objective of this study is to provide a more holistic view of the customer’s role and value cocreation within digital health-care services. This study emphasizes the necessity of the co-creation of value within the health-care sector and introduces a paradigm shift through the digitization of value …
Warmer climates boost cyanobacterial dominance in shallow lakes
2011
Dominance by cyanobacteria hampers human use of lakes and reservoirs worldwide. Previous studies indicate that excessive nutrient loading and warmer conditions promote dominance by cyanobacteria, but evidence from global scale field data has so far been scarce. Our analysis, based on a study of 143 lakes along a latitudinal transect ranging from subarctic Europe to southern South America, shows that although warmer climates do not result in higher overall phytoplankton biomass, the percentage of the total phytoplankton biovolume attributable to cyanobacteria increases steeply with temperature. Our results also reveal that the percent cyanobacteria is greater in lakes with high rates of ligh…
Changes in physiological astigmatism of human eye during accommodation in emmetropes (Conference Presentation)
2017
Introduction: Most young emmetrope eyes are far from ideal and have some degree of minor spherocylindrical error including also physiological astigmatism. Because of the changes in the shape of optical interfaces, pupil size, eyelid pressure, tear film, body posture, binocularity and accommodation astigmatism is considered as constantly dynamic phenomenon (Cheng et al, 2004). The purpose of this study was to evaluate and quantify changes in physiological astigmatism during accommodation. Method: Twenty young emmetropes with mean age 24 ± 4 years were selected for the study. Refraction and accommodative response were measured monocularly for dominant eye with an open-field infrared autorefract…
Precursor frequency can compensate for lower TCR expression in T cell competition during priming in vivo.
2006
The factors controlling clonal dominance of cytotoxic T lymphocyte (CTL) responses are currently not well understood. To study the functional impact of the strength of the interaction of a T cell with an antigen-presenting cell in this context, we established a new mouse model comprised of two T cell receptor (TCR)-transgenic strains expressing the identical TCR in differing amounts, hence providing two CTL clones with different avidities but identical specificity and affinity. Utilizing this new model, we show that upon antigen challenge higher-avidity CTL expand at the expense of moderate-avidity CTL in vivo if present in equal numbers. Beyond this, moderate-avidity T cells can also contr…
Codominance of Lactobacillus plantarum and obligate heterofermentative lactic acid bacteria during sourdough fermentation
2015
Fifteen sourdoughs produced in western Sicily (southern Italy) were analysed by classical methods for their chemico-physical characteristics and the levels of lactic acid bacteria (LAB). pH and total titratable acidity (TTA) were mostly in the range commonly reported for similar products produced in Italy, but the fermentation quotient (FQ) of the majority of samples was above 4.0, due to the low concentration of acetic acid estimated by high performance liquid chromatography (HPLC). Specific counts of LAB showed levels higher than 10(8) CFU g(-1) for many samples. The colonies representing various morphologies were isolated and, after the differentiation based on phenotypic characteristics…
Spatial and temporal changes in Actinobacterial dominance in experimental artificial groundwater recharge.
2008
Abstract Artificial groundwater recharge (AGR) is used in the drinking water industry to supplement groundwater resources and to minimise the use of chemicals in water treatment. This study analysed the spatial and temporal changes of microbial communities in AGR using two test systems: a nutrient-amended fluidized-bed reactor (FBR) and a sand column. Structural changes in the feed lake water (Lake Roine), FBR, and sand column bacterial communities were determined by denaturing gradient gel electrophoresis (DGGE) and the length heterogeneity analysis of amplified 16S rRNA genes (LH-PCR). Two clone libraries were created to link the LH-PCR results to the dominant bacterial groups. The lake w…
Limit on the production of a light vector gauge boson in $\phi $ mesondecays with the KLOE detector
2012
We present a new limit on the production of a light dark-force mediator with the KLOE detector at DAPHNE. This boson, called U, has been searched for in the decay phi --> eta U, U --> e+ e-, analyzing the decay eta --> pi0 pi0 pi0 in a data sample of 1.7 fb-1. No structures are observed in the e+e- invariant mass distribution over the background. This search is combined with a previous result obtained from the decay eta --> pi+ pi- pi0, increasing the sensitivity. We set an upper limit at 90% C.L. on the ratio between the U boson coupling constant and the fine structure constant of alpha'/alpha < 1.7x10^-5 for 30<M_U<400 MeV and alpha'/alpha < 8x10^-6 for the sub-region 50<M_U<210 MeV. This…
TOURISM POLICY IN LATVIA - FROM A TOP-DOWN TO A COLLABORATIVE APPROACH
2020
In 2019, Latvia drafted a National Development Plan [NDP 2027] for the next period, which also comprises actions for the development of the tourism sector. Unlike previous practices, approaches to drafting a common plan and developing and implementing tourism policy have changed significantly. The aim of the research is to describe the process of developing a tourism development plan, analyse the use of the latest planning and policy implementation approaches and evaluate the framework of the plan. A qualitative research strategy - a case study was used. The main research methods are document analysis, in-depth interviews and participatory observations. The process of drafting a new tourism…
